Bowl Blending?

I state over and over that there is really no down side to bowl work (porting). I know some will not agree...but a good 'bowl job' will not destroy port velocity, very important to street engines. As Rumblefish correctly stated, it picks up low lift flow, mostly under .500 lift. The seats and their angles are very important in very low lift flow, as is the criticle short side (port floor) as it 'turns' down over seats. Also back cutting of the valves has a big effect on low lift flow. A good 'bowl job', With good seats and back cutting of the valves and you will have a GOOD piece indeed. I would not hesitate to perform this work even on 'torque only' motors such as RV's, trucks ect. As for numbers...About 40 horsepower can be expected, 20 cfm or so depending on how 'deep' you go into the port. + = more, - = less. Even with factory manifolds, intake and exhaust...you will benifit. As always gentlemen(?) LOL, LOL. JMHO. Good luck. Terry.
